Bishop of Nocera and humanist historian, Paolo Giovio (1483-1552) assembled a private collection of portraits of virtuous men that formed the basis of this posthumous publication, the first illustrated edition of a work that Giovio had originally published without woodcuts in Florence in 1551. The woodcuts added are by Tobias Stimmer (1539-1584). A recent Newberry fellow, Professor Susan Gaylard pointed out that Giovio in his lifetime had envisioned a version of his work illustrated by hand-colored woodcuts. Our copy appears to be the sole one in which the author’s desire for hand-colored illustration was realized, at least for the frontispiece here displayed. William Traheron, who owned this volume, was a Protestant dissident and a translator from the Spanish of a history of the Roman emperors, copies of which are in the Newberry’s collection.
